Excerpt: I bought 2 older versions of this unit five years ago. Both have worked flawlessly during that time, until a couple weeks ago when one of them must have developed an internal short. One side quit providing power. So, I immediately went to B&H and ordered a new one.
Excerpt: This was purchased as a replacement. This is same as the @ Atvia branded unit which I owned and lasted for 6 years before it died. This unit so far has operated as reliable as my other united. I've also owned APC brand.
Excerpt: Price is about the only "Con" I can think of. But then again this is not a regular surge protector ! This unit has 8 A/C plug-ins, 4 of them say just Surge, the other 4 say Surge/Battery Back-up. Depending on what your protecting, you have up to 45 min. of battery power.
Summary: This is a smaller UPS than we have previously purchased, this model does not have a large internal battery like the next model up does, but somehow it still provides all the power we need in outages.
Summary: This CyberPower Standby CP550SLG 550 VA Desktop UPS is very nice. This is their newer model that connects easily with a USB cable to my iMac and I don't even need to load any software. This model works off Apple's built-in power management software.
Summary: I bought another name brand and it just didn't have the reserve power this unit has. I've more than enough time to shut down any programs, print out what I need and shut down with plenty of time to spare. A great vaule for the money!
